My main field of work and area of interest in recent years is the energy transition, seen from an economic perspective. The interaction of public policy and business. The micro- and macroeconomic implications, as well as the public-private collaboration instruments most adequate to ensure a speedy and efficient transition, coherent with the urgency and scope of the challenge. Increasingly interested in circularity and biodiversity issues i.e. natural capital as the other piece of the ecological transition.In this defining challenge for the planet, we need to acknowledge that harmony with the natural world is an important part of societal welfare. Public policy and particularly economic policy should be adapted accordingly
